Anti-lock braking system (ABS)

The ABS prevents the wheels from locking during braking.

The anti-lock brake system (ABS) makes a significant contribution to active safety. However, do not expect the ABS to reduce braking distance in all cases. On roads covered with loose gravel or fresh snow over a slippery surface, where slow and careful driving is required, the braking distance may even increase slightly.

How the ABS works

A self-check takes place as soon as the vehicle reaches approx. 6 km/h. A pump noise may then be audible.

If a wheel has a circumferential speed that is too low compared with the actual vehicle speed and tends to lock, the system reduces the brake pressure for that wheel. This control process is felt as pulsations in the brake pedal, accompanied by noise. The driver knows

when the wheels are about to lock (ABS control range).

For the ABS to function optimally in this control range, keep the brake pedal fully depressed and do NOT pump the brakes!

CAUTION!

Even the ABS cannot overcome the laws of physics.

Always keep this in mind, especially when roads are slippery or wet. When the ABS enters the control range, immediately adapt your speed to the road conditions and traffic situation. The greatest safety available must not encourage you to take unnecessary risks - risk of accident!
